Description
This is the nut that attaches the cam timing gear to the camshaft on BMC A-series and B-series engines (Mini, Austin Healey Sprite, MG Midget to 1974. MGA, MGB). The nut is very thin and can only be used a few times before they strip out. It is a good idea to change this nut every time you change the camshaft. Cross Ref.# 311-500
